Zippy is a confident, loud and enthusiastic guy who loves to be the center of attention. He has a habit of yelling over others and and is very competitive. Although he can be quite mean (He calls Bungle "Bungle-bonce) He usually apologises in the end, and does care about his friends.
Due to his frequently loud behaviour and silly voice getting him into all sorts of trouble, other characters in Rainbow occasionally zip his mouth shut for a short time, rendering him unable to talk. On at least one occasion he unzips himself, although he appears unable to do so on most occasions. Zippy is well known for his love of food, and in many episodes is seen eating.
